When I import videos from my iPhone 6s I put it on my Synology Media Box to play on my Sony UHD TV. HD files play perfectly and look great. However, when I try to play a 4K file from my phone the TV tells me the video format is not supported? So how do I get native 4K files to play on my TV? Thank you all!
